The first of two films about the Amazon basin with its immense river system and vast rainforests. Every year for six months, the Amazon floodplain is entirely submerged, forcing residents (plants, animals and man) to adapt to an environment half in, half out of water. The first film reveals some of the wildlfie species of the area during the flooded half of the year, including dolphins, fruit-eating fish and the white-furred, bald-headed uakari monkey.
